16 Tory and MPs and 8 Liberal Democrats rebelled against the Government's plans to change planning permission laws in the House of Commons this evening.
Efforts to appease Tory MPs angry at the plans appeared to fall flat, and the Government saw its Commons majority cut to just 27.
Under the proposals drawn up by the Government, home-owners with detached houses will be able to build a single-storey extension of up to 26ft without the need for planning permission.
Home-owners with any other house will be able to extend to 19ft .
